DIY Darkness Detector using LDR 🌑 | LED Glows in Dark!

Описание: Learn how to make a simple Darkness Detector using an LDR (Light Dependent Resistor) and an LED. This fun and educational electronics project is perfect for beginners and helps understand how light sensors work. When it gets dark, the LED automatically turns on!

💡 Components Used:

LDR (Light Dependent Resistor)

LED

Resistor ( 330 ohm for led , 10k ohm for LDR )

Transistor (TP 122 / NPN BC 547)

Power Source

Breadboard & Connecting Wires

🔧 Working Principle:
The resistance of the LDR increases in the dark, triggering the LED to glow. It’s a practical application of a basic light sensor circuit.
